Reverse cross reference links
I am a seminarian. I take notes in Microsoft Word through the duration of a course, adding in (WIKI) links to various resources in my Logos lirbary as well as putting scripture references in my notes (2 Sam 9:9, etc.). Logos does a great job of picking up the linking/cross referencing when I add in my notes in as a personal book. For instance, in my notes I'm able to however over that scripture link and see the reference, or any of he WIKI links I've manually added in.
My suggestion comes in that I would like there to be a cross reference from my source back to my notes. For instance, when I'm browsing my bible, it would be awesome if there were some indicator at a particular scripture passage (2 Sam 9:9) that I have another document that links or references this passage. So when I'm reading my scriptures, preparing for a homily, I can be notified that this particular passage has been talked about in my notes from these 2 or 3 classes.
I know the cited by tool has this functionality, but it would be awesome to have it built right into the resources as I'm reading them. So if I'm reading Saint Thomas' Summa Theologiae, I can see that we talked about Question 39 Article 1 in my Ecclesiology class...etc.
This feature would be extremely powerful!
